UHV-H100A
UHV-H100A Contact Resistance Tester is mainly used for test the contact resistance of the high voltage circuit breaker analyzer, it has the features: 1. High current: The circuit resistance tester adopts new power supply technology, which can continuously output high current for a long time, overcoming the drawbacks of instantaneous current in pulse power supply. It can effectively breakdown the oxide film on switch contacts and obtain good test results 2. Strong anti-interference ability: Under severe interference conditions, the last digit of the LCD screen can be stable within ± 1 word range, with stable readings and good repeatability 3. The circuit resistance tester has a long service life: all use high-precision resistors, effectively eliminating the impact of environmental temperature on the measurement results. At the same time, the use of military connectors enhances the vibration resistance performance 3. Convenient to carry: small size and light weight

UHV-310
UHV-310 Transformer winding deformation tester is mainly composed of laptop and the main host, it is mainly used for test the deformation of the transformer winding. It has the feature: 1. The hardware movement adopts DDS dedicated digital high-speed frequency scanning technology to accurately diagnose faults such as winding distortion, bulging, displacement, tilting, inter turn short circuit deformation, and inter phase contact short circuit.2. The acquisition and control system adopts highly integrated microprocessors, selects precise and highly stable components, and high-speed dual channel 16 bit A/D sampling (on-site testing changes the tap changer, resulting in significant changes in waveform curves). The measurement repetition rate for the same phase is above 99.5%.3. The instrument has dual measurement system functions of linear sweep frequency measurement and segmented sweep frequency measurement, and is compatible with the measurement modes of two current domestic technology
